What causes a bird to fly?

A wing creates lift by imparting a downward momentum to the air flowing above and below it. The rate of change of momentum is equal to Force (Newton's 2nd law), and therefore a reaction force pushes the wing up, producing lift (Newton's 3rd law).

The act of imparting a downward momentum ("downwash") to the air results in an air pressure differential around the wing. If you know the pressure above the wing and the pressure below the wing, and the wing area, you can calculate the lift force on the wing since Force = Pressure x Area. If you don't know the pressures, you can get a rough estimate if you know what the average air velocities are above and below the wing. By employing Bernoulli's Principle, you can calculate a pressure difference corresponding to the difference in velocity.

Note that there is no requirement that the air molecules separating at the leading edge and flowing below the wing meet up with the same molecules that flow over the top. This is called the "equal transit time theory" and is a popular science myth that unfortunately has found it's way into flight manuals and even some undergraduate texts. However, aerodynamicists have known ever since they started doing wind tunnel testing that the air flowing over a lifting wing reaches the trailing edge sooner than the air below it. This can be explained in terms of the circulation theory, which is an advanced concept.

What bird Soars?

Many birds of prey, such as eagles, hawks, and vultures, soar high in the sky by riding thermal air currents. This behavior allows them to conserve energy while searching for food or migrating long distances.

What bird with red stomach eats with it's head upside down?

The bird you are referring to is likely the northern cardinal. They are known to eat with their head upside down by bending their neck to reach hanging fruit or seeds below them. This unique feeding behavior helps them access food sources that may otherwise be difficult to reach.

What percentage of birds fly south for the winter?

Approximately half of bird species migrate south for the winter. This can vary depending on the region and specific bird populations. Some birds migrate to warmer climates to find food and suitable breeding grounds during the colder months.

How many animals can fly backwards?

There are a few species of hummingbirds that can fly backwards, thanks to unique wing structures and rapid wing movements. This ability allows them to feed on nectar more efficiently and hover in place.

What part of the world do the cardinal birds come from?

cardinals are north American birbs,found more in the east ,but range expanding westward over the rockies.

Are birds afraid of squirrels?

Birds are often wary of squirrels because squirrels can raid bird feeders and nests for food, which can be a threat to birds and their eggs. However, the fear level can vary among different bird species and depends on the individual bird's behavior and experience with squirrels. In general, birds will avoid areas where they feel threatened by squirrels.

Where did elephant birds live?

Elephant birds lived in Madagascar, an island off the eastern coast of Africa. They were flightless birds that resembled modern-day ostriches and stood about 10 feet tall, making them one of the largest birds to ever exist.

Where does a grosbeak bird live?

fruits, seeds, insects, etc.

Depends on which grosbeak-- Evening or Black-headed or Rose-breasted Grosbeak...

All grosbeaks are seed eaters basically, but will take some berries and insects. The blue grosbeak is the only one in the family that may take insects more than seeds or berries.

What is the size of the white tailed ptarmigan?

The White-tailed Ptarmigan is a grouse of alpine (above treeline) habitats. It is the smallest grouse in North America (total length 30 to 31 cm, weight 295 to 440 grams), and the only species of grouse with white tail feathers. It possesses cryptic plumage that changes annually from white in winter to grayish-brown in summer. The sexes are similar in body size, shape, and winter plumage.

Breeding season males have a conspicuous necklace of coarsely barred brown and black breast feathers, while female plumage is predominantly brown and black with yellowish barring. Male plumage is generally more brown and gray than in the female. Males possess scarlet eye combs that are especially conspicuous during the breeding season; females have less conspicuous and smaller salmon-colored eye combs. In winter, in addition to the completely white plumage, the legs are heavily feathered to the ends of the toes, creating a snowshoe effect for walking on snow (Choate 1960, Braun et al. 1993).

Are birds warm or cold blood?

All birds are warm blooded as they maintain their bodies at a constant temperature. They get energy from burning their food, to keep their temperature above ambient. If they get too hot they depend on evaporation of water from the tissues of the lungs to cool them down.

What harm do house sparrows present to native birds?

House sparrows can be harmful to native birds by competing for nesting sites and food resources, leading to a decrease in biodiversity. They can also introduce diseases to native bird populations, impacting their health and survival. Additionally, aggressive behaviors displayed by house sparrows can disrupt the breeding success of native bird species.

What is the temperature for a blue crowned bird to live in?

Blue-crowned birds, such as the Blue-crowned Conure, thrive in temperatures between 65-85°F (18-29°C). These birds are sensitive to extreme temperatures, so it's important to provide a stable and comfortable environment within this range to ensure their well-being.

What are quella birds?

What are the uses of outer covering of birds?

The feathers, or plumage, of a bird have the following purposes:

  • In many bird species, the male's brighter colouring or markings help attract a female
  • Waterproofing - most birds have feathers that help to waterproof them against rain or the water of the habitat in which they live
  • Camouflage - many birds have plumage that enables them to blend in with their surroundings
  • Insulation - some species of birds, which live in colder climates, have feathers which are arranged and structured so as to insulate them better against the cold

Bird smaller than an eastern bluebird with brighter blue feathers with black on wings?

A male indigo bunting fits this description. It is smaller than an eastern bluebird and has brilliant blue plumage with black on its wings. The indigo bunting's coloring is vibrant, especially when seen in direct sunlight.

How do you cheer budgies?

How many do you have? If you only have one I would say he is clearly lonely and would benefit from some social contact from another budgie. They are social creatures and need contact with other birds to be fulfilled.

Another solution (if you don't want to buy another bird) is toys. A mirror is by far the best and should relieve both boredom and loneliness. Your budgie will think the reflection is another bird and will be thrilled with the new "playmate". The best mirrors for this are the ones sold in pet stores that come with little bells on the bottom because the budgie thinks the tinkling sound is the other bird talking. One mirror is probably around $2 or $3. Be sure to hang them where next to your budgie's perch, and he will feel like he is surrounded by friends! Just be prepared for the incredible racket; my budgie, Feathers, talks to his friends for hours on end!

You might also try a plastic budgie toy. I bought one for my Feathers and he doesn't seem to like it as much, but sometimes I will find him pecking and chirping at it. You can also try toys that are just bells, but keep an eye on the plastic parts because they can get broken and your bird might think the pieces are something to eat.

Another thing might be to do different things when playing with your budgie. My Feathers loves water, so I sometimes put my hand under a (very light) stream of water from the tap. He climbs right down onto my fingers and bathes and plays in the water.

Good luck. Hope that helps.
